Has anyone ever successfully made a gold mirror in a test tube, much like the silver Tollens reaction does?
I understand that it really depends on your reducing agent as gold will be much more easily reduced. And you can't prepare that soluble ammine complex
like with silver.
I found one description that used AuCl3 in combination with Ethanol / Acetaldehyde and Glucose to get a slow reaction. But it would never
mirror out at all.
Perhaps some of you guys has an idea.

What do you actually want to achieve? You can use a flame to vapour deposit gold onto glass or you can use a standard lustre paint to fire it on to
either glass or ceramic. There is electrodeposition onto a suitably prepared surface as well. No point going into details until we get some idea about
the objective you wish to accomplish.

I am going to answer that question for myself, Chemetix. I have always fancied samples of Cu, Ag and Au for my element collection: identical test
tubes with the metal mirror inside and ampouled shut to avoud dust and damage.
Ag is well documented. Cu and Ag less so.
